f(x)=-4x-3 Find the slope and y-intercept
f(x) = -4x - 3
The slope-intercept form of an equation, where m = slope and b = y-intercept.
y = mx + b
Since your equation is already in the slope-intercept form,
y = mx + b
y = -4x - 3
Slope m = -4
y-intercept b = -3
Thank you , Helper. You and Ms. Sue have been a major part in my completing this. I cannot begin to tell you guys how thankful I am. Both of you have been a blessing. THANK YOU SO VERY MUCH!!
You're welcome :)
To find the slope and y-intercept of the function f(x) = -4x - 3, we can use the standard form of a linear equation, which is y = mx + b, where m represents the slope and b represents the y-intercept.
In this case, -4x - 3 can be rewritten as y = -4x - 3. Now, we can identify the slope and y-intercept by comparing this equation with the standard form.
The coefficient of x, which is -4, represents the slope of the line. Therefore, the slope of the function f(x) = -4x - 3 is -4.
The constant term, which is -3, corresponds to the y-intercept. Thus, the y-intercept of the function f(x) = -4x - 3 is -3.
In summary, the slope is -4 and the y-intercept is -3 for the function f(x) = -4x - 3.
